Vaccination Against Newcastle Disease and Infectious Bronchitis

Introduction

“…We can easily envisage him developing into a committed Parliamentarian, like his friends, as the town quickly became a garrison. 214 Woodford was clearly at this stage leaning towards Presbyterianism, and when in London he favoured the preaching of Calamy and his following. Most of the ministers with whom Woodford was associated followed this trajectory, as did his father-in-law, Robert Haunch.…”

Newcastle Disease Immunization Studies

“…Rhode Island Red chickens of two dif-ferent ages, 4 days and 4| weeks, originating from a parent flock free from chronic respiratory disease (CRD) and previously vaccinated with Newcastle disease and infectious bronchitis (IB) dust vaccines (Markham et al, 1955) were used. In all lots in each trial, division as to sex was approximately equal.…”

Dietary Aureomycin Chlortetracycline and Immune Response to Newcastle Disease and Infectious Bronchitis

“…The methods employed in these studies are described elsewhere (Markham et al, 1955). The challenge test for NDV was done by intranasal instillation of a 1:10 dilution of the GB strain (Boney, 1951) Aureomycin was mixed with either the feed or water.…”

“…In the course of a series of field trials which were designed primarily to study the influence of various levels of chlortetracycline on the weight gains and mortality of broilers, the birds were vaccinated with a combination Newcastle disease-infectious bronchitis vaccine in the form of micronized dusts and aerosols (Markham et al, 1955). Blood samples were collected prior to and at intervals after vaccination for the purpose of determining the immune response to the new vaccine.…”
